Web4 The differential of z p(X,∗) is the alternating sum of the maps induced by restricting cycles to codimension 1 faces. Define the higher Chow homology groups by CH p(X,n) = H n(z p(X,∗)), n,p ≥ 0. If X is locally equi-dimensional over k (e.g., X is smooth), let zq(X,n) be the free abelian group on the integral closed subvarieties Z ⊂ X × ∆n with the property WebThis identifies Chow cohomology classes with certain functions on the set of cones in ∆; a function ccorresponds to a class in Ak(X) if it satisfies the linear equations in formula (2.1) below. We call these functions Minkowski weights. The Chow homology of a complete toric variety can have torsion, and some of these groups can vanish ...
WebFeb 24, 2016 · We construct the so-called niveau spectral sequence, similar to the coniveau one, for Borel–Moore homology; as a consequence, we deduce that Borel–Moore homology groups are isomorphic to Chow groups (Corollary 3.9 ); then we show the compatibility of this isomorphism with respect to push-forward, pull-back and refined … Web2.4. Higher Chow Groups. Note that higher Chow groups is a homology theory, so we have a spectral sequence associated to ‘coniveau’ filtration (indeed it is a niveau filtration). Theorem 2.15 ([Blo86a, Section 10]). For any quasi-projective algebraic k-scheme X, there is a spectral sequence (4) Ep,q 1 (b) = M x∈X(p)
